CNA Isolation Precautions 3 — Questions and Answers
Question 1: A patient with active tuberculosis (TB) is placed in a negative-pressure room. What type of isolation is this?
- Contact precautions
- Droplet precautions
- Airborne precautions (Correct answer)
- Standard precautions
Correct answer: Airborne precautions
Active TB requires airborne precautions, including a negative-pressure room, because TB is transmitted via tiny airborne particles that can travel long distances.
Question 2: When removing PPE after caring for a patient on contact precautions, what is removed LAST?
- Gloves
- Gown
- Mask
- Hand hygiene is performed last, not PPE removal (Correct answer)
Correct answer: Hand hygiene is performed last, not PPE removal
Hand hygiene is the final step after all PPE has been removed, not a piece of PPE itself; gloves are typically removed first, then gown, then mask/eye protection.
Question 3: A resident in a long-term care facility has C. difficile diarrhea. Which hand hygiene method is MOST effective against C. diff spores?
- Alcohol-based hand rub
- Soap and water handwashing (Correct answer)
- Antiseptic wipes
- Waterless hand sanitizer
Correct answer: Soap and water handwashing
Soap and water is required for C. difficile because alcohol-based hand rubs do not effectively destroy C. diff spores.
Question 4: Which color-coded isolation sign typically indicates droplet precautions in many US hospitals?
- Yellow (Correct answer)
- Orange
- Pink
- Blue
Correct answer: Yellow
Many US facilities use yellow signs to designate droplet precautions, though color coding can vary by facility policy.
Question 5: A CNA is caring for a patient on airborne precautions. The patient needs to be transported to radiology. What must the PATIENT wear during transport?
- N95 respirator
- Surgical mask (Correct answer)
- Full face shield
- No mask is required
Correct answer: Surgical mask
During transport, the patient on airborne precautions should wear a surgical mask to contain respiratory secretions and protect others in the hallway.
Question 6: Which of the following actions VIOLATES isolation precautions for a patient in contact isolation?
- Wearing gloves before entering the room
- Leaving the door open while providing care (Correct answer)
- Wearing a gown when direct contact is anticipated
- Placing soiled linens in a designated bag inside the room
Correct answer: Leaving the door open while providing care
The door to a contact isolation room should remain closed to prevent the spread of organisms via contact with surfaces or personnel in hallways.

- 12 hours
- 24 hours (Correct answer)
- 48 hours

For meningococcal disease, droplet precautions are maintained until 24 hours after effective antibiotic therapy has begun.
